Are the Double Bell 190rnd short magazines any good?

[ISAB]

I'm relatively new and got myself one of the Chicom Type 63 rigs. The regular AR15 platform magazines fit snugly enough in the pouches but I've been looking at getting 2 or 3 magazines modelled after the early M16 magazines or something like it of that size, because the pouches were made for 20 round mags.

The Double Bell M4/M16 190rnd magazines seems to be that size, but I'm just wondering if anyone has any experience with them and whether they're good or bad.

Thanks in advance.
